Historical statistics for September 2025 to August 2026, not live status. For today’s flights, check with American Airlines.
American on BOS to MCO lands a B, 3 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That rests on 284 flights. The strongest carrier on the route with a full sample, Delta Air Lines, flew 1,257 at 75.5% on time.
The US average over the same twelve months is 77.3%, so there is little to separate American on BOS to MCO from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
American against every carrier on BOS to MCO
American flew 284 of the 4,605 flights on BOS to MCO, about 6% of it. Its 80.7% on time is 11 points better than the route as a whole, which runs 69.5%. Ranked by on-time rate it is first of six carriers on the route, where the range runs from American at 80.7% to Southwest at 50.0%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
The choice of carrier is not cosmetic here. Delta Air Lines arrives on time 75.5% of the time; Spirit Airlines manages 58.5%. Sample sizes sit next to every figure, because a two-point gap across 389 flights means less than a ten-point one.

Spirit Airlines cancels 4.9% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Departure window
When American runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 284 flights.
There are not enough flights in each departure window to split American's BOS to MCO record by time of day without the percentages moving on noise. The headline rate of 80.7% is the reliable figure here.
Across the year
American on BOS to MCO through the year
- Oct–Dec 202514 flights—
- Jan–Mar 2026100 flights74.5%
- Apr–Jun 202699 flights86.9%
- Jul–Sep 202671 flights85.3%
Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 80.7% on time across 284 flights.
American on BOS to MCO did not run the same all year. Its best quarter was Apr–Jun 2026 at 86.9% on time and its weakest Jan–Mar 2026 at 74.5%, a swing of 12 points on roughly 95 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Wednesday is the strongest day at 94.1% on time and Saturday the weakest at 75.4%, a spread of 19 points.

Share of 275 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 40 departures that left 15 minutes late or more, only 2 made it up before arrival. In the other direction, 15 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at MCO.
The worst days
Worst days for American on BOS to MCO
The latest arrival of the period was on 10 January 2026, 11 hours 39 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across January, December, July and February, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 10 January 2026 | 11 hours 39 minutes | Late-arriving aircraft |
| 23 December 2025 | 8 hours 21 minutes | Late-arriving aircraft |
| 2 July 2026 | 8 hours 21 minutes | Carrier |
| 15 February 2026 | 6 hours 11 minutes | Carrier |
| 26 July 2026 | 5 hours 13 minutes | Extreme weather |
Delay causes
Why American runs late on this route
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,776 reported delay minutes.
- 38%Late-arriving aircraft
- 35%Carrier
- 20%National Airspace System
- 7%Extreme weather
38% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,776 reported delay minutes here, that single category outweighs weather by 5 to one. The split is drawn from 5,776 reported delay minutes.
The largest share of delay minutes, 35%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,017 of the 5,776 delay minutes reported here.
Cancellations run at 2.82%, against 1.89% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
Connections and stage length
What a delay here costs
9.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 1,121 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg is a different operation and performs like one: it runs 66.8% on time across 284 flights, 14 points below this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 14 points of difference.
One caution: this is a thin sample. 284 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking American on BOS to MCO
Put together: the delay figures matter less here than the 2.82% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 275 completed flights over 12 months sit behind that.
